For crispy air fryer Brussels sprouts, trim and halve 1 pound of sprouts, dry them thoroughly, then toss them with 1 tablespoon olive oil, 1/2 teaspoon kosher salt, 1/4 teaspoon freshly ground black pepper, and 1/2 teaspoon garlic powder. Air-fry the sprouts cut-side down at 375°F for 14–18 minutes or at 400°F for 10–14 minutes, shaking or turning them halfway through.
This easy Air Fryer recipe produces Brussels sprouts with deeply browned, crunchy edges and tender centers in about 25–30 minutes from start to finish. A squeeze of lemon juice, a sprinkle of Parmesan, a drizzle of balsamic glaze, or a pinch of red pepper flakes gives the finished vegetables a bright, savory finish without hiding their naturally nutty flavor.

These air fryer Brussels sprouts are a fast answer to the question of how to make vegetables exciting. The dry, high heat creates caramelized edges while the centers stay pleasantly tender, giving each bite a contrast between crisp leaves and soft, savory flesh.
Only a tablespoon of olive oil is needed for a full pound of sprouts. Garlic powder, kosher salt, and freshly ground black pepper provide a dependable base, while the optional toppings let you take the recipe in a bright, cheesy, sweet-tangy, or spicy direction.
The Air Fryer is especially helpful when your oven is occupied or you want a smaller batch without heating the kitchen. For another easy vegetable side, you can also try our crispy Air Fryer corn recipe.
- Quick: Prep takes about 10 minutes, and cooking takes 12–18 minutes depending on the temperature and model.
- Small-batch friendly: One pound makes 3–4 servings.
- Flexible: Lemon, Parmesan, balsamic glaze, and red pepper flakes each bring a different finish.
- Weeknight ready: The ingredients are simple enough for a last-minute side dish.
Ingredients You’ll Need
Choose firm Brussels sprouts with compact leaves and a fresh green color. Sprouts can vary in size, so cutting the larger ones in half helps everything cook at a similar rate.
- 1 pound Brussels sprouts: Trimmed and halved, with loose or damaged outer leaves removed.
- 1 tablespoon olive oil: Helps the seasonings cling and encourages browning.
- 1/2 teaspoon kosher salt: Brings out the sprouts’ natural sweetness.
- 1/4 teaspoon freshly ground black pepper: Adds gentle warmth and sharpness.
- 1/2 teaspoon garlic powder: Gives the vegetables a savory garlic note without adding moisture.
The finishing ingredients are optional rather than part of the basic seasoning mixture. Lemon juice adds freshness, Parmesan contributes salty richness, balsamic glaze supplies a sweet-tart contrast, and red pepper flakes bring heat.

How to Make It Step-by-Step
Step 1: Trim the stem ends from the Brussels sprouts with a small sharp knife, then peel away any loose, discolored, or damaged leaves. Cut the larger sprouts in half from stem to top, while very small sprouts can be left whole or halved according to your preference.
Step 2: Pat the prepared sprouts completely dry using paper towels or a clean kitchen towel. This is one of the most important parts of the recipe because surface moisture creates steam and can prevent the outer leaves from becoming crisp.
Step 3: Place the dry sprouts in a large bowl and add the olive oil, kosher salt, black pepper, and garlic powder. Toss thoroughly until the oil and seasonings coat the cut sides and outer leaves without leaving dry pockets at the bottom of the bowl.
Step 4: Preheat your Air Fryer to 375°F–400°F, depending on the model and the level of browning you prefer. A temperature of 375°F generally takes about 14–18 minutes, while 400°F generally takes about 10–14 minutes.
Step 5: Arrange the sprouts in the basket with as many cut sides down as possible. Keep them in a mostly single layer and leave room between pieces; if the basket is packed tightly, cook in two batches rather than sacrificing airflow.
Step 6: Air-fry until the bottoms become deeply browned and the centers are tender when pierced with a fork. Shake the basket or turn the sprouts halfway through cooking so the loose leaves brown evenly and no single side receives all the heat.
Step 7: Taste one sprout after cooking and adjust the seasoning if needed. Add lemon juice, Parmesan, balsamic glaze, red pepper flakes, or a small additional pinch of salt only after the sprouts are hot and crisp.
Step 8: Serve immediately while the browned leaves have their best texture. If you are making multiple batches, place the finished sprouts on a plate rather than sealing them in a covered container, which can trap steam.
How to Get the Crispiest Results
Drying is more important than adding extra oil. After washing the sprouts, give them plenty of time to drain, then pat them thoroughly before seasoning.
Cut-side placement also matters. Setting the flat cut surface against the hot basket encourages direct browning, which creates the dark, savory crust that makes this recipe so appealing.
- Do not overcrowd: Air must move around the sprouts, so use two batches if necessary.
- Keep the seasoning simple: Garlic powder works well because it does not introduce extra liquid.
- Check early: Air fryers vary, so begin checking near the lower end of the suggested cooking time.
- Finish after cooking: Add balsamic glaze and Parmesan at the end to keep them from scorching.
- Serve promptly: The sprouts are crispiest right after they leave the basket.

Serving Ideas and Flavor Variations
As a side dish, these sprouts work with roasted chicken, pork, steak, fish, or a simple grain bowl. Their savory garlic seasoning is versatile enough for a holiday table but quick enough for an ordinary weeknight.
For a bright finish, toss the cooked sprouts with 1–2 teaspoons of lemon juice. Add Parmesan while they are still warm so the cheese clings lightly to the leaves without becoming overly heavy.
Balsamic glaze gives the crisp leaves a sweet-tangy contrast. Use the listed 1 tablespoon after cooking, drizzling it lightly so the glaze accents the sprouts instead of making them soggy.
If you like heat, add a pinch of red pepper flakes just before serving. For a hearty Air Fryer meal, serve the sprouts beside bacon-wrapped chicken tenders or pair them with bacon scallops for a special dinner.
Storage and Reheating
Leftover Brussels sprouts can be stored in a covered container in the refrigerator, although their leaves will soften after chilling. Keep any Parmesan or balsamic glaze separate when possible so the sprouts do not absorb extra moisture during storage.
To reheat, return the sprouts to the Air Fryer until warmed through and crisp around the edges. Avoid covering them while reheating, since trapped steam works against the browned texture you want.
If the sprouts seem dry after reheating, add lemon juice or a small amount of balsamic glaze at the table. A fresh finishing sprinkle of salt can also restore their flavor without requiring additional oil.
These storage tips are also useful when preparing a larger meal in advance. Cook the sprouts close to serving time whenever possible, because freshly air-fried vegetables always have the firmest centers and crispest leaves.
Crispy Air Fryer Brussels Sprouts
Ingredients
Method
- Trim the stem ends from 1 pound of Brussels sprouts and remove any loose, yellow, or damaged outer leaves. Cut larger sprouts in half; very small sprouts may be left whole or halved.
- Pat the Brussels sprouts very dry with clean kitchen towels or paper towels. Toss them with 1 tablespoon olive oil, 1/2 teaspoon kosher salt, 1/4 teaspoon black pepper, and 1/2 teaspoon garlic powder until every piece is evenly coated.
- Preheat the air fryer to 375°F–400°F, following the temperature that suits your model. Arrange the sprouts mostly in a single layer with the cut sides facing down, leaving space around them for hot air to circulate.
- Cook at 375°F for about 14–18 minutes or at 400°F for about 10–14 minutes. Shake the basket or turn the sprouts halfway through, then continue cooking until the cut sides are deeply browned and the centers are tender.
- Transfer the hot Brussels sprouts to a serving bowl and taste for seasoning. Finish with 1–2 teaspoons lemon juice, 1 tablespoon Parmesan, 1 tablespoon balsamic glaze, a pinch of red pepper flakes, or additional salt as desired.
Notes
Final Thoughts
This Crispy Air Fryer Brussels Sprouts Recipe proves that a few everyday ingredients can produce a memorable vegetable side. The essential details are simple: trim the sprouts, dry them thoroughly, season evenly, place them cut-side down, and give them enough space for hot air to circulate.
Choose 375°F for a slightly gentler cook of about 14–18 minutes or 400°F for a faster cook of about 10–14 minutes. Since Air Fryer models differ, use the deeply browned cut sides and tender centers as your best doneness guide rather than relying on the clock alone.
Finish the sprouts with lemon, Parmesan, balsamic glaze, or red pepper flakes, then bring them to the table right away. Once you taste those crisp edges and tender, nutty centers, this quick recipe is likely to become a regular part of your weeknight rotation.
